CASH REGISTER AND INDICATQR.

SPECIFICATION forming part of Letters Patent No. 524,812, dated August21, 1894.

Application filed April 9, 1894.

To all whom it may concern.-

l 3e it known that 1, CHARLES W. SHIBELEY, a citizen of the UnitedStates, residing at Dayton, in the county of Montgomery and State ofOhio, have invented a certain new and useful improvement in CashRegisters and Indicators, of which the following is a description,reference being had to the accompanylcllg drawings, forming part of thisspecifica- My invention relates to that class of cash registers andindicators which are inclosed within a casing having a lid which isopened to obtain access to the interior of the machlne and which isnormally locked and the key kept in the possession of the proprietor. Itconsists of whatmay be called a lid-arrester, and is designed to be usedin connection with the lid-registerwith which many machines of thisclass are equipped. These lid registers consist of sets of registeringwheels mounted either upon the lid itself or an ad acent part of thecasing and automatically operated by the opening and closing of the lid.Their purpose is to preserve a record of the openings of the lid so thatthe same cannot be opened without the knowledge of the proprietor, thelatter being supposed to make a note of the number exhibited by theregister at the last inspection of it so that at its next-inspection thenumber exhibited by the register should be a unit higher than that lastnoted by him. One defect in the practical use of these lid registersheretofore has been that, inasmuch as it was necessary to open the lidsome distance in order to actuate the lid register, it was possible fora person to open it far enough to obtain access to the interior of themachine with a suitable instrument without affecting the lid reglster.Thus by picking the lock or obtaining a key thereto it was possible totamper with the mechanism of the machine without risk of detection bythe lid register.

My present invention consists in the provision of novel means, which Iterm the lid arrester, for compelling a full or definite opening of thelid each time it is unlocked and slightly opened, so that it will not bepossible to open the lid far enough to obtain any access to the interiorof the machine, and

then close it, without having first opened it sufficiently to actuatethe lid register. The means which I employ for this purpose may now bedescribed by reference to the accompanying drawings, in which- Figure 1represents a vertical cross section of the casing and some of the partsof a cash register equipped with my invention; and Fig. 2 a detail viewof one of the ordinary forms of lid registers employed upon machines ofthis class.

The case A, of the usual or any suitable shape and construction, isprovided with the hinged lid B adapted to be swung upward and rearwardto obtain access to the interior of the machine and provided with alook, not shown, for locking it in its closed position. Hinged to theunder side of this lid at or near one edge is a curved arm O whichpasses through a guide slot in the plate D projecting laterally from aplate E secured to the side of the casing. The arm 0 is provided in itslower edge near its rear end with a notch F which, when the lid is swungupward and rearward to full open position, catches over the front wallof the guide slotin the plate D and serves to hold the lid in its openposition. When the lid is to be closed the arm 0 is pressed rearward todisengage its notch h from the plate D, whereupon the lid will drop toclosed position by gravity. The upper rear edge of the arm C is serratedfor some considerable distance from the upper end of the arm, and theserrations co-operate with a pawl G pivoted to the plate E. The pivotalarrangement of this pawl in relation to the arm 0 is such that theserrations in the arm are free to slip under the pawl as the lid isopened and the arm lifted, while the engagement of the pawl with theserrations, so long as the pawl remains in its normal position, willprevent any return movement of the lid toward closed position. springlatch H whose pointed 'nose bears against the under rear side of theheel of the pawl G serves to yieldingly press the pawl into engagementwith the serrations on the arm 0. At the lower rear endof the serrationsthe upper rear edge 'of the arm 0 is provided with a projection, or theserrated portion of the arm is suificiently cut away to form a shoulderat the lower end of the serrations, which projection or shoulder whenthe lid has been opened and the arm 0 lifted a predetermined distancewill contact With the under side of the front end of the pawl and liftit to and beyond the position shown in dotted lines, throwing the heelof the pawl downward past the pointed nose of the latch H, which willthen maintain the pawl in its new position and out of engagement withthe arm 0. Thelid is thereupon free to be closed again, and when it isclosed a shoulder upon the rear edge of the arm 0 at the upper end ofthe serrations will contact with the front end of the pawl and returnthe latter to norxnal position, its heel slipping upward past the noseof the springdatch II. In the present instance about one-half or alittle less of the edge of the arm 0 is shown as serrated, so that thelid can be closed again after having been about onehalf opened, thisbeing sul'licient to insure the operation of the lid registerhereinafter referred to, but if desired a greater portion or nearly theentire upper edge of the arm 0 may be serrated.

The plate E forms one of the side plates of a metal casing whichincloses the arresting devices above described to prevent access beinghad to them when the lid is partially opened, the other side plate ofthe casing being shown removed or cut away to expose the parts within.

In Fig. 2 is shown a lid registerof familiar construction andarrangement, consisting of a train of registering wheels inclosed withina casing I secured upon the under side of the lid B adjacent its hingingline, and having a stud or pin K connected with the actuating pawl ot'the primary wheel projecting downward through the casing into positionto strike a cross bar J of the casing when the lid is closed. At eachclosing of the lid the pin K will be forced into the casing I and theprimary wheel of the train advanced one number to register suchoperation of the lid.

Having thus fully described my invention, I claim- In a cash registerand indicator, the combination, with the casing and its hinged lidadapted to be swung upward to obtain access to the interior of themachine, of a lid register for preserving the number of openings andclosings of the lid, a serrated arm hung to the underside of the lid, apawl co-operating with the serrations on the arm and projections orshoulders at either end of the serrations, and a spring-latchco-operating with the pawl, substantially as and for thepurposedescribed.
